Abstract :
This paper reports on practical study of a switchable dual-frequency oscillator for 60-GHz binary FSK modulation, using a 0.15 mum commercial GaAs p-HEMT technology. The oscillator obtained an output power of 1.8 dBm at 61.43 GHz with a phase noise of -65dBc/Hz at 100 kHz offset and -87dBc/Hz at 1MHz offset to the carrier at the free-run state. A 500 Mbit/s FSK modulation was confirmed with the developed oscillator. This type of oscillator is feasible for of multi-gigabit data rate FSK modulation.
